7 Claims. (Cl- 5.3

The" present invention relates to improvements in cigar machine pasting.devices and constitutes a con inuat n in part of my former app ic tiSerialNo. 266,561, which wasissued as Patent No. 2,292 317, to whichreference may be had forfurther details not herein set forth.

In. cigar making machines, particularly those in which fresh bunches aremade, a binder is placed on a bunch rolling table prior to the enclosureof a. charge of filler in the binder and paste is applied to the binderon the rolling tablebefore the char e enclosing operation occurs. Thepaste conveyor automatically travels between paste receiving positionand" 11 bunch rolling table where it delivers paste once during eachmachine cycle of operations. Itsometimes happens that the binder isimproperly positioned on the rolling table or not positioned onthetabl'e at all before the paste .conveyorreaches paste deliveringposition; and in'that event the paste is applied, not to the binder, butto the table itself. This is undesirable. because it. not only soil sbut also damages the rolling apron.

An object of the present invention is the production of a device whicheliminates this trouble by preventing the. paste conveyor fromdelivering paste to the bunch rolling table when a binder is not inproper'position thereon.

Insome types of cigarmachines, various mechanisms such as the supportfor the roller coacting' withithe rolling apron form obstacles pastwhich the paste applying arm must travel. 'It' is an 010- ject of thepresent invention to provide an improved arm which will carry the pasteapplying member in' elevated position past said obstacles and over thebinder, and which will then cause the paste applier to descend intoengagement with the binder lying upon the rolling apron.

A further object is to provide an improved and simplified pasteapplying.mechanism for applyingpaste to a binder located upon'the'rollingapron;

Other objects and features of the invention will appear asthe-description'of the particular physical embodiments selected-toillustrate the invention progresses.

In the accompanying drawings, which form a part of this specification,like characters of reference have been applied to corresponding partsthroughoutthe several views which makeup'the drawings; in which: r

Fig. 1 is aside elevation of the binder leaf paster mechanism, showingits relation to the rolling mechanism.

Fig, 2' is-a-planview of Fig. 1 (the rolling mech anism being omitted inorder to more clearly show the paster mechanism). t

Fig. 3 is aside elevation of a modified binder leaf" paster mechanism,showing its relation to. the rolling'mechanism.

Fig, 4 is an end view of Fig; 3 (the rolling mechanism being omitted inorder to more-clearlyshow the paster mechanism).

Referring to Figs. 1 and 2, the. paste applier, Which in the embodimentshown is a roller Ill; isadjustably attached to an arm I I, which ispivotally connected to'a lever 12 attached to a shaft I3 in abearingblcck l4, secured to the frame of the: machine. Connection [5 ispivoted" to arm ll adjustabl'y attached to a rod l6 which isslidablymounted in a pivot H on lever I 2, and carries; acamfoilower H3.Also secured to shaft I3 is a lever l9 which is adjustably connected tothe driving mechanismof the machine;

Thedrive of the p'aster mechanism is so timed with relation to the drivefor the binder rolling mechanism of the machine that the paste rollerlilis swung up into position, deposits paste on the binder; B, while thebinder rollingmechanismis at rest, and is withdrawn from the path of theoncoming rolling mechanism parts, the operation of' which is well-knownto -those skilled in the art. While: the paster "mechanism occupies itsre tractedposition, as shown in Figs. 1 and 2, the pasteroller IO'rid'eson the paste supply wheel- 20, which is continuously rotated byconventional andwellknown means (not shown). The wheel ispartlysuhmergedin the paste in pot 2i;

Atthe-proper time in the machine cycle, the pastor mechanism operates toswing away from the supply wheel'20', but the applier It remains incontact with the-wheel 20' until the cam follower ldcon-tacts thecircular trackof cam 22. When the follower runs 01f the circular track22 and above the straight portion 23 thereof, it permits arm II to"swing av certain amount under the action of spring 24, one end of whichis attached to atrigger 25 which is pivoted at H upon arm l2, andtheother end of which is attached to a trigger block 26. mounted upon rodHi. It will Ice-observed that trigger :block 26 is provided withshoulders 21 with which the nose of the trigger is adapted to engage inorder to maintain the applier I 0- above the binder leaf section B onthe rolling apron 28 until the trigger is tripped to allow the 'applierto bemoved against the binder. A slot 29' is formed. in the triggerblock through which the trigger may move when its nose; 30--isdisengaged from shoulder 21. It will "be observed; therefore, thatspring 24 performs plier would result in an undesirable situation, and

in all probability tend to cause the applier to lift the binder B fromthe apron 28, the above described trigger mechanism has been providedfor insuring that the applier cannot move into engagement with thebinder B until the maximum has been done, applier ID has been locatedover the binder at the proper point A, and mechanism to be presentlydescribed is then set into operation to effect the movement of theapplier to a position C for application of paste to the binder.

At the extreme position of movement of arm l2, trigger 25 through spring24 tends to keep follower l8 in contact with straight cam section 23,and through the engagement of nose 30 with shoulder 21 of the triggerblock 26 holds the paste applier in fixed position away from binder B,until adjustable trip screw 32 mounted upon the trigger abuts aprojection 33 fixed to the cam 22. The movement of the arm l2 againstthe projection 33 causes the tripping of the trigger with the net resultthat nose 30 is swung away from engagement with shoulder 21, and isforced by spring 24 into slot 23, thereby allowing the spring to pullthe applier down upon the binder section B. Thus as the paste applier Iis permitted to descend upon the binder leaf, and as the return movementof the paster mechanism starts anew, applier l0 deposits the requiredquantity of paste upon the binder B.

The paste applier remains in contact with the binder leaf until the camfollower l8 moves back onto the circular portion of cam 22, whereupon itcauses a relative longitudinal movement between trigger 25 and block 26.After the paste applier l3 has been brought into engagement with supplywheel 20, spring 24 rocks the trigger on its pivot I! so as to engagenose 3|] thereof with shoulder 21, thereby resetting the triggermechanism for the next cycle of the machine.

All necessary adjustments for properly timing the several periods ofaction are arranged for.

The binder leaf B is placed on the apron 28 before the bunch rollingmovement starts, and is held in a predetermined position on the apron bysuction in a conventional manner well understood by those. skilled inthe art. 'The paste is applied to the binder to secure the binder whenit is wrapped about the filler by the rolling apron 28.

At the completion of the rolling operation, the bunch is dropped overthe edge of the rolling table 3| ready to be-transferred by conventionalmeans (not shown) for the wrapping and finishing operation.

In order to prevent the paste applier I0 from descending upon therolling apron 28 when no binder leaf B is in position, the operatorpulls a rod 34 connected to cam 22 and locks it in a desired position,as shown by the dotted'lines in Fig. 1.

When the arm I2 is swung toward the binder, the arm II will be held inelevated position by swing of arm II has been effected. When this Hlatch 21, 30 and since the trip plate 33 has been retracted by means ofrod 34, the trip screw 32 will not engage therewith. As a result, thearm will remain elevated throughout the normal paste applying cycle. Thecam roller l8 will also be constrained to remain over the circularsector of cam 22 and this too would prevent the arm II from droppingpaste applier I0 onto the apron. Two different precautions are therebyprovided to prevent the past applier from placing paste upon the apronwhen no binder leaf is present.

Set screw 32 provides a convenient device for increasing or decreasingthe amount of time allowed for the paste applier [0 to remain in contactwith the binder B. By turning screw 32 in one'direction or the other, itis possible to fix the point at which it is desired to have pasteapplier I0 fall into engagement with the binder leaf B. Suitableadjustments are also made to regulate the swing of arm l2 so that itwill have completed its forward swing at the time the applier i0 isunlatched. As arm I2 starts its return swing, paste applying roller I0travels on top of the binder leaf B, applying paste thereto. When camroller l8 strikes circular cam 22, roller [0 is lifted out of engagementwith the binder leaf B. The point at which paste applier Ill is liftedout of engagement with binder leaf B can be regulated by set screw 35.By means of the foregoing adjustment, it will be possible to regulatethe location and area to which paste is applied.

An adjustment to vary the swing of paster lever i2 can be made byshifting the position of connecting rod 36 in lever l9.

In the modified embodiment shown in Figs. 3 and 4, the paste applier isa roller 45 adjustably attached to an arm 4|, which is pivotallyconnected to a lever 42 attached to a shaft 43 in a bracket 44 securedto the bed 45 of the machine. Also fastened to shaft 43 is a lever 46which is provided with a ball shaped stud 41 engaging in a socket 48carried by a rod 49 which is adjustably connected to the drivingmechanism of the machine.

The drive of the paste mechanism is so timed, with relation to the drivefor the binder rolling mechanism of the machine, that the paste roller43 is swung into position to deposit paste on the binder B while thebinder rolling mechanism is at rest, and is withdrawn as the bunchroller commences to roll the binder B about a filler charge in a mannerwell known to those skilled in the art.

While the paster mechanism occupies its retracted position, as shown indotted lines in Fig. 3, the paste roller 40 rides on the rim of thepaste supply wheel 50, which is continuously rotated by a shaft 5| (Fig.4) supported in a housing 52 of the machine. The end of shaft 51 isprovided with an aperture 53 in which a stud 54 is slidably mounted. Thehead 55 of stud 54 is provided with a V-shaped depression 56 adapted toreceive the pointed end 51 of shaft 58; the opposite end of said shafthas a similar pointed end which fits into a V-shaped depression 59 in astud 6i] fastened in the upper end of an arm 6| which extends from thebracket 44. The head 55 is equipped with a pit; 62 adapted to engage thevertically mounted pin 63 secured in shaft 58 and in this manner impartmotion to said shaft. The stud 54 is normally retained in the positionshown in Fig. 4 by a compression spring 64-inserted in the aperture 53.The paste supply wheel 50 is adjustably attached to shaft 58 by meansof'a screw -.6;5. .and:is positionedso; thatitnelower. porion: thereof;rotates: inv the pasteinipot. 6t
